I'm walking around the edge of Riddy Wood and spoted these seed heads. They belong to common hogweed which are a delicious edible species. Many of you will have heard of the non native giant hogweed which can cause severe burns with it's phototoxic juices but our common variety is delicious and just about every part of it is useful as a wild food. These dry seeds in particular make a wonderful spicy ingredient, somewhat similar to ginger, in baking.
I'll post another update soon to help you tell the difference between this and giant hogweed and expect many more posts about hogweed.
